Kotatsu table

I just logged onto the game to check this, and my Sims are still able to take naps in the kotatsu. No, they don't lay down on the floor when they do it. They do the sitting up naps, like people do in Japan on the trains or at work during break time. They do sleep when they do it though, and I've seen people nap that way in real life kotatsu too.

(I had to check this, because I was a little worried they removed another Japanese element from the game. It's still in there though.)
